I need help with properties of rhombus, rectangles and squares

Montano1993 [528]

Answer:

∠ROK = 36°
∠CKO = 96°
∠C = 60°

Step-by-step explanation:

The same-side angles at each base are supplementary, so ...

∠ROC = 180° -120° = 60°

Because the trapezoid is isosceles, 60° also the measure of ∠C.

The angle sum theorem tells you ...

∠COK +∠ROK = ∠ROC

24° + ∠ROK = 60°

∠ROK = 36° . . . . . . subtract 24°

The sum of angles in ΔCKO is 180°, so ...

∠C +∠COK +∠CKO = 180°

60° +24° +∠CKO = 180°

∠CKO = 96° . . . . . . . . . . . . . subtract 84°

Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error:

Yakvenalex [24]

Answer: 112

Step-by-step explanation:

Given : Significance level : $\alpha=1-0.95=0.05$

Critical value: $z_{\alpha/2}=1.96$

Margin of error : E = 9%=0.09

The estimated proportion of caret : p =0.38

Now, the formula to find the sample size :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

i.e. $n=(0.38)(1-0.38)(\dfrac{1.96}{0.09})^2$

$=111.738390123\approx112$

Hence, the required minimum sample size = 112

What is the value of x? Enter your answer in the box.

kherson [118]

This is an equilateral triangle because all the sides are the same length shown by the tic marks. This means that the angles are also all congruent. so...
S=T=R this also means that all angles are 60 degrees because all triangles angles added together are 180 degrees. so that means that you put all of the equations equal to 60. but if u are looking for x only here is the answer
7x+4=60
7x=56
x=8
